BACKGROUND

1. Field

Apparatus and methods consistent with exemplary embodiments relate to a device and a method of controlling the device.

2. Description of the Related Art

Along with the introduction of various electronic devices, in many cases, a plurality of users may use a single device together. When a user logs onto a device, the device may be set by the user that has logged on. The device may operate under set conditions. For example, in the case of a medical imaging apparatus, a user that wants to capture a medical image may input an ID and a password to log onto the medical imaging apparatus. The medical imaging apparatus may display a user interface (e.g., an index or a tool shown on a viewer) that is set with respect to the ID that is logged in, or capture a medical image according to set imaging conditions.

However, in the example above, the user may have to inconveniently log in by inputting his or her ID and password by oneself to set the device to personally-preferred settings. Also, because pieces of configuration information of the users are stored in the device, when the users want to use another device, the users may have to newly set the other device.

The matters defined in the description, such as detailed construction and elements, are provided to assist in a comprehensive understanding of the exemplary embodiments. However, it is apparent that the exemplary embodiments may be practiced without those specifically defined matters. Also, well-known functions or constructions may not be described in detail because they would obscure the description with unnecessary detail.

In the present specification, “configuration information” refers to information that indicates conditions related to operations of a device, for example, displaying a user interface or capturing images. The “configuration information” may also include information indicating conditions related to operations of devices.

For example, when the device is a medical imaging apparatus, configuration information may include setting values (i.e., setting values related to a user interface), date format, time settings, indexes to be displayed via a viewer, functions to be included in a tool bar and displayed via the viewer, addresses (e.g., URLs) of remote services, display formats of the addresses of the remote control tools, and display formats of names of imaging targets. The date format may refer to a setting value that indicates how to display the current date. The time settings may refer to a setting value about the current time that is to be set in the device. Types of the indexes to be displayed via the viewer may include types of indexes to be displayed among setting values or estimated values (e.g., in a case of an X-ray imaging apparatus, doses and exposure indexes) that are set in the device. The functions to be included in the tool bar may refer to a list of function buttons that are frequently used by the user among functions of the device, for example, drawing a circle, drawing a quadrilateral, inputting text, and a virtual ruler.

As another example, in a case that the device is a medical imaging apparatus (e.g., an X-ray imaging apparatus), configuration information may include setting values related to capturing images (i.e., conditions related to operations of the device), for example, a setting value related to automatic deleting of images, whether to automatically confirm images, whether to automatically transmit images, whether to use auto exposure control (AEC), whether to store an original image, and whether to estimate a dose-area product (DAP). The setting value related to automatic deleting of images may indicate setting whether to automatically delete images in the device and setting a ratio between all images to images to be deleted. Whether to automatically confirm images may indicate setting whether to automatically store captured images without confirmation of the user. Whether to automatically transmit images may indicate setting whether to automatically transmit captured images to another device, for example, a picture archiving and communication system (PACS). Whether to use AEC may indicate setting whether to apply the AEC when capturing images. Whether to store the original image may indicate setting whether to store an original captured image. Whether to estimate the DAP may indicate setting whether to estimate the DAP when capturing images.

Also, “user configuration information” may indicate configuration information that is determined by the user to use the device.

Also, in the specification, a “medical imaging apparatus” may include not only an apparatus for capturing medical images, for example, an X-ray imaging apparatus, a tomography apparatus, a magnetic resonance imaging (MRI) apparatus, and an ultrasound imaging apparatus, but also a system for storing, reading, and searching for medical image information, for example, PACS.

Also, in the present specification, a “mobile device” may include, but is not limited to a mobile phone, a smartphone, a tablet personal computer (PC), a personal digital assistant (PDA), a handheld personal communication system (PCS), or a navigation device.

Also, when a “device” is a medical imaging apparatus in the present specification, a “user” may be, but is not limited to, a medical expert, such as a medical doctor, a nurse, a medical laboratory technologist, or a technician who repairs a medical apparatus.

Also, in the present specification, a “user interface” may indicate an apparatus for interacting with a user, software for interacting with a user, or a combination thereof. For example, when a device is an X-ray imaging apparatus, a user interface may include, but is not limited to, values related to capturing images such as Kvp, mA, mSec, or mAs, or a tool bar for manipulating the X-ray imaging apparatus.

When the user manipulates the switch, the input interface may generate signals that correspond to an instruction that is input by the manipulation of the switch, i.e., a preparation signal and an irradiation signal, and output the signals to the high voltage generator 621 that generates a high voltage.

The controller 612 may control respective locations of the X-ray irradiator 620 and the detector 630, capture timing, and an imaging condition according to an imaging condition included in the user configuration information acquired by the configuration information acquiring interface 611. The controller 612 controls the high voltage generator 621 and the detector 630 according to the configuration information, X-ray irradiation timing, X-ray strength, and an X-ray irradiation area. Also, according to the imaging condition, the controller 612 may adjust a location of the detector 630 and control an operation timing of the detector 630.

Also, the controller 612 may generate a medical image of an object by using image data that is received from the detector 630. The controller 612 may receive image data from the detector 630, remove noise of the image data, adjust dynamic ranges, perform interleaving operation, and thus generate a medical image of the object.

FIG. 7 is a flowchart of a process of controlling the device 110, according to one or more exemplary embodiments.

In operation S710, the device 110 recognizes a mobile device that is located within a short distance, by using the detector 410. The mobile device 120 within the short distance may be detected with various methods according to exemplary embodiments. For example, the device 110 may use sound waves or strength of signals received from the mobile device 120 to estimate a distance between the device 110 and the mobile device 120. When a distance between the device 110 and the mobile device 120 is the same as or less than a predetermined value based on the strength of the signals received from the mobile device 120, the device 110 may determine that the mobile device 120 is within the short distance. Also, when the mobile device 120 broadcasts wireless communication signals (e.g., BLE signals) that include device ID information for identifying the mobile device 120, the device 110 may recognize the mobile device 120 based on the received wireless communication signals. Also, to transmit and receive more pieces of data, the device 110 may connect wireless communication services according to another communication technique (e.g., WFD) with the mobile device 120, by using a communication interface in the configuration information acquiring interface 420.

In operation S720, the device 110 determines whether the detected mobile device 120 is registered in the device 110. For example, the device 110 may compare the device ID information received in operation S710 with device ID information that is stored in the device 110. When one of the pieces of device ID information stored in the device 110 corresponds to the device ID information received in operation S710, the device 110 may determine that the mobile device 120 is registered in the device 110. If the device 110 determines that the detected mobile device 120 is not registered in the device 110, the device 110 continues in operation S730. Otherwise, the device 110 continues in operation S740.

In operation S730, the device 110 performs a mobile device registration process. The mobile device registration process is a process for registering the mobile device 120 to the device 110. To register the mobile device 120 to the device 110, the device 110 may output a user interface for selecting whether to register the detected mobile device 120. For example, FIG. 9 is a diagram of a user interface that displays a list related to the detected mobile device 120.

FIG. 9 is a diagram of a user interface for registering the mobile device 120 that is displayed on the device 110, according to one or more exemplary embodiments. Referring to FIG. 9, the user may select the mobile device 120 to register from the list related to the mobile device 120, and register the selected mobile device 120 to the device 110 by pressing a ‘Register’ button. To register the mobile device 120, the device 110 may acquire ID information of the mobile device 120, which includes at least one selected from device ID information and user ID information, from the mobile device 120. The device 110 may register the mobile device 120 to the device 110 by storing the acquired ID information. The device 110 may transmit a registration request to the mobile device 120 to acquire the ID information related to the mobile device 120.

In operation S735, the device 110 determines whether the mobile device registration process is complete, i.e., whether the mobile device 120 is registered to the device 110. If the device 110 determines that the mobile device registration is complete, the device 110 continues in operation S740. Otherwise, the process ends.

In operation S740, the device 110 acquires user configuration information from the mobile device 120. For example, the device 110 may acquire the user configuration information from the mobile device 120 via short distance wireless communication (e.g., Bluetooth or WFD). In this case, the device 110 may transmit a request for the user configuration information to the mobile device 120. Alternatively, when a signal is received from the mobile device 120 in operation S710, the device 110 may register the mobile device 120 by using ID information included in the received signal. However, exemplary embodiments are not limited thereto. The user configuration information may be not stored in the device 110.

In operation S750, the device 110 performs an operation based on the acquired user configuration information. Operations of the device 110 may include all operations that may be performed by the device 110. For example, based on the user configuration information, the device 110 may determine user interface elements (e.g., a tool bar) to be included in a user interface or information (e.g., an indicator related to imaging when the device 110 is a medical device) to be displayed via the user interface. The device 110 may output a user interface that is configured based on the user configuration information. Alternatively, when the device 110 is a medical imaging apparatus that may capture medical images, the device 110 may set an imaging condition for capturing medical images based on the user configuration information. The user configuration information may include at least one setting value for capturing medical images. The at least one setting value may include at least one selected from a dose, an exposure index, Kvp, mA, mSec, mAs, AEC, density, a size of a focal spot, a collimator correction value, physical resolution of the detector 630, and logical resolution of the detector 630.

The device 110 may transmit image information that is related to an image stored in the device 110 to the mobile device 120. In this case, the device 110 may be a medical imaging apparatus. The image information may include, for example, at least one selected from a distance between an object and the X-ray source 622 when the stored image was captured, a dose, an exposure index, Kvp set in the device 110, mA set in the device 110, mSec set in the device 110, mAs set in the device 110, estimated Kvp, AEC, density, a size of a focal spot, a collimator correction value, temperature of the detector 630, sensitivity of the detector 630, physical resolution of the detector 630, logical resolution of the detector 630, a deviation index, spatial resolution, detector calibration time, captured portion, image capture number, and a retake rate (a rejection rate). The ‘captured portion’ refers to information that indicates which object is captured in an image. The ‘image capture number’ may refer to information that indicates the total number of image-capturing performed by the device 110 or the number of image-capturing performed by the user of the mobile device 120 using the device 110. The ‘retake rate’ may refer to a rate of images that are not successfully captured and have to be captured again. Because information such as the ‘retake rate’ is provided to the mobile device 120, the user of the mobile device 120 may determine whether a setting value according to the user configuration information related to the mobile device 120 is effective for capturing images.

FIG. 8 is a flowchart of a process of controlling the mobile device 120 according to one or more exemplary embodiments.

In operation S810, the mobile device 120 determines whether a registration request or information is received from the device 110. If the mobile device 120 determines that the registration request or information is received, the mobile device 120 continues in operation S820. Otherwise, the mobile device 120 continues in operation S830.

In operation S820, the mobile device 120 performs a registration process. For example, the mobile device 120 may transmit information related to the mobile device 120 to the device 110, so that the mobile device 120 may be registered to the device 110.

According to other exemplary embodiments, the mobile device 120 may repeatedly transmit short distance wireless communication signals that include device ID information for identifying the mobile device 120. In this case, operations S810 and S820 may be omitted because the device 110 may register the mobile device 120 based on the transmitted short distance wireless communication signals.

In operation S830, the mobile device 120 receives a configuration information request from the device 110.

In operation S840, the mobile device 120 transmits user configuration information that is stored in the mobile device 120 to the device 110.

According to other exemplary embodiments, the mobile device 120 may receive image information that is related to an image stored in the device 110, from the device 110. The image information may include, for example, at least one selected from a distance between an object and the X-ray source 622 when the stored image was captured, a dose, an exposure index, Kvp set in the device 110, mA set in the device 110, mSec set in the device 110, mAs set in the device 110, estimated Kvp, AEC, density, a size of a focal spot, a collimator correction value, temperature of the detector 630, sensitivity of the detector 630, physical resolution of the detector 630, logical resolution of the detector 630, a deviation index, spatial resolution, detector calibration time, captured portion, image capture number, and a retake rate (a rejection rate). The mobile device 120 may display the received image information via the display 580 so that the user of the mobile device 120 may check the image information related to the image stored in the device 110.

FIGS. 10 and 11 are diagrams of operations of the device 110 when one mobile device or at least two mobile devices are detected, according to one or more exemplary embodiments.

Referring to FIG. 10, when only one mobile device, i.e., the first mobile device 120-1, is near the device 110, the device 110 receives user configuration information from the first mobile device 120-1, and sets an operation condition of the device 110 based on the received user configuration information. For example, the device 110 displays a user interface 1000 that is configured according to a condition that is set by a user of the first mobile device 120-1. That is, the device 110 may be set to a state in which the user of the first mobile device 120-1 logs onto the device 110 by inputting his or her ID and password.

Another mobile device may approach the device 110 while the device 110 is set based on the user configuration information that is received from the first mobile device 120-1. Referring to FIG. 11, the first mobile device 120-1 and a second mobile device 120-2 are located near the device 110. In this case, the device 110 determines whether to change settings of the device 110 according to user configuration information that is stored in the second mobile device 120-2. A method of determining whether to change the settings of the device 110 may vary depending on exemplary embodiments. For example, the device 110 may set a grade of a user for each registered mobile device. When a user of the second mobile device 120-2 has a higher grade than the user of the first mobile device 120-1, the device 110 may acquire user configuration information from the second mobile device 120-2 and change the settings of the device 110. As another example, when the second mobile device 120-2 is detected, the device 110 may output the user interface 1100 for selecting whether to change the settings of the device 110. The user may select whether to change the settings of the device 110 via the user interface 1100.

When the settings of the device 110 are changed according to user configuration information that is stored in the second mobile device 120-2, the device 110 acquires the user configuration information from the second mobile device 120-2. The device 110 changes the settings of the device 110 based on the user configuration information that is received from the second mobile device 120-2. For example, as shown in FIG. 11, the device 110 displays a user interface 1110 that is configured based on the user configuration information received from the second mobile device 120-2.
